I guess there is a club for everything and everyone in business. As the GMAT Club says:
“The idea for this website came from the GMAT forums where brilliant posts made by arduous test takers were soon lost and forgotten. GMATClub.com was started with the objective of building a community of students, a community where the sole objective is learning and contributing to others learning, a community bound together selflessly by a single goal – The B-School Admission”
They have been recommending my book on entrepreneurship for those people that enjoyed the WSJ article on Success and Failure last week.
Excellent site!
I find the use of a wiki interesting for a site like that. It is often difficult to find moderators for a site like that, and otherwise eventually they give way to a flood of spam. Interesting site!
